Question 181054: Given a rectangle that is 43 cm longer than it is wide. Express the perimeter (in cm) of a rectangle in terms of its width w. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! L=W+43
PERIMETER=2L+2W
PERIMETER=2(W+43)+2W
PERIMETER=2W+86+2W
PERIMETER=4W+86
PERIMETER-86=4W
4W=PERIMETER-86
W=(PERIMETER-86)/4
